Kwikset 300CSLSQT-514 Casey Lever Privacy Door Lock

Product Description

The KWIKSET 300CSLSQT-514 is a Casey lever-style privacy door lock featuring a square rose trim plate, a 6AL latch, and an RCS strike plate, finished in Matte Black. Designed for interior residential applications, this privacy lock allows a room to be secured from the inside without a keyed cylinder. The lever-and-rose assembly mounts to standard door preps and is installed by finish carpenters, general contractors, or experienced DIYers during new construction or remodel work. The included 6AL latch and RCS strike provide a complete, ready-to-install hardware set in a single package.

This privacy lock is suited for interior doors in residential settings where occupancy privacy is needed, such as bathrooms, bedrooms, and similar spaces. The Matte Black finish coordinates with a broad range of interior door hardware styles. The square rose design offers a contemporary profile that fits modern and transitional interior aesthetics. No exterior key access is provided, which is appropriate for privacy applications where emergency release from the exterior is handled by a small tool or coin through the emergency access hole on the outer lever.
